Having a no-show for a father and with his mother always off somewhere else (getting drunk or partying), Yusuke has grown up in a very neglectful environment. He's short-tempered, impulsive, merciless and likes to intimidate those who are afraid of him. Underneath his bold, cocky attitude, he has a joking and kind nature. Yusuke has also had the bad luck of having to deal with so many cruel and despicable people at such a young age, Iwamoto being among them.
